head to head
Ketsui: Kizuna Jigoku Tachi asks more than Resogun, and the gap is execution.

Execution · Pure Mechanics
Cave's hardest bullet hell, built on suicidal close-range scoring and merciless execution demands.

Execution · Practiced Mastery
A voxel-based arcade shooter where precise movement and optimal human-rescue sequencing drive score.
Ketsui: Kizuna Jigoku Tachi leans Execution (Pure Mechanics); Resogun leans Execution (Practiced Mastery).
Ketsui: Kizuna Jigoku Tachi leans clearly harder on execution.
Ketsui: Kizuna Jigoku Tachi
Point-blank chip harvesting in bullet storms, brutal physical ceiling
Resogun
Precise overdrive timing and bullet-threading at high speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ketsui: Kizuna Jigoku Tachi
Enemies follow fixed scripts
Resogun
Scripted enemy formations only
Resogun leans a little harder on variance, though the gap is small.
Ketsui: Kizuna Jigoku Tachi
Deterministic patterns, trivial randomness
Resogun
Particle-based destruction and some randomised enemy entry points
Ketsui: Kizuna Jigoku Tachi leans a little harder on optimization, though the gap is small.
Ketsui: Kizuna Jigoku Tachi
Multiplier chip routing is a solved-route discipline
Resogun
Keeper rescue sequencing and phase timing are fully learnable
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
